PV Tool Award DEK Solar
HouY i Cell Metallization Platform
SINCE ITS INCEPTION IN 2008, DEK Solar has set out to be a solar process pioneer. The company, already market- leading suppliers of screen printing equipment worldwide, recognised that its decades of global print process expertise gave it a strategic advantage, providing the company with the know-how to develop a complete range of solutions to help photovoltaic manufacturers boost cell effi ciency and reduce the total cost of ownership of their lines.
I LM-2 LCO-PERC Laser Machine
INCREASING CELL EFFICIENCY is the most effective way to reduce the cost of solar power, and PERC (Passivated Emitter and Rear Contact) is one of the technologies that meet the balance between manufacturing cost and effi ciency.
InnoLas used its 15 years of experience in laser processing for the PV industry to design the cost effective ILM-2 production platform for lowest maintenance costs and best Cost of Ownership in the market. The ILM-2 platform is further optimized for easy integration into existing production lines and reduces handling steps if integrated e.g. via conveyor interface prior to a screen printer line or directly after a passivation tool.
HouYi a 1350 wafers per hour, highly reliable metallization platform with a small footprint is DEK Solar’s latest innovation. It builds on the performance of DEK’s PV 1200 platform, with innovations that have delivered even greater reliability, enhanced print quality and further improved throughput.
As a result of these enhancements, no other metallization platform on the market is now able to provide the same levels of reliability, print quality, and throughput, delivering lowest cost of ownership within as small a footprint as HouYi.
HouYi has been specifi cally designed to meet the most pressing needs of today’s PV fi rms.
InnoLas Solutions sees increasing demand for PERC solutions that can be adapted fl exibly to current and future production line designs and requirements. The company designed the ILM-2 as a modular machine concept that can be used as a stand-alone or in-line system, with the option to use different laser sources.
The ILM-2 offers our customers a future-proof 24/7 production solution with an excellent uptime. This high volume production machine to open the passivation coating of PERC cells by a laser lift off process.
The ILM-2 comprises an improved laser and optical setup which allows perfect control of the contact opening at the highest process speed. It enables a dashed line pattern layout enhancing the cell effi ciency.
For the fi rst time a novel dashed line pattern layout was enabled at high process speed. Such the cell effi ciency can be increased at lowest cost of ownership.

GridTOUCH
THE PATENT PENDING GridTOUCH contacting system is a solution that addresses the new market need of contacting busbarless cells for IV/ EL performance measurements. This innovative system is a measurement jig consisting of an upper frame and a bottom plate. Both the plate and frame have a grid of wires.
These grids are aligned perpendicularly to each other thus ensuring an optimum connection of all fi ngers on the front side of the solar cell and a highly accurate evaluation of the fi ll factor (FF and other key IV parameters.
The GridTOUCH also ensures that the shadowing on the cell is minimised and that the IV measurement is both precise and highly reproducible. The system
